Added vertex color support to the DXF loader, fixed a minor bugs. Coordinate system issue still unsolved.

Modified GenVertexNormals to take always the cross product of the first and the last normal of a face as face normal.
Material implementation for LWO - seems to work, but there are some issues with highly complex models.
Added some LWO test models
Cleaned up the ./test dir - converted some BMPs to JPG to save space,
Finished the matrial property list in jAssimp, some other changes, too. The Java part of the API should be working now.
